shouldn't we

Of course we should. This is a *major* experimental program,
with easily a dozen groups investigating the question of whether
composition affects gravitational fields.

So far, though, not one speck of evidence has been found to
suggest that ``some forms of energy do not curve space-time.''
There are strong limits for electrostatic and magnetstatic
energy,

Reference, please.

At high enough electrostatic fields the vacuum sparks. An atomic
nucleus with Z approaching 1/(Fine Structure constant) would cause
pair production at its surface via vacuum decay and spontaneously
lower its atomic number via inverse beta-decay. Magnetic fields have
no such apparent limits.

strong interaction energy,

Reference, please.

Res ipsa loquiter given the mechanism and the Standard Model.

and gravitational binding energy,

Reference, please.

Black holes.

with somewhat weaker limits on kinetic energy and the
energy of the parity-conserving part of the weak interactions.

Reference, please.

How can you hope to converse upon a topic for which you have no
knowledge? Haul your butt over to arXiv.org and look up the basics.
